125³x-²=25²x+²​

Answer 1

Respuesta:

${(125)}^{3} {x}^{ - 2} = {(25)}^{2} {x}^{ + 2} \\ \frac{ {(125)}^{3} }{ {(25)}^{2} } = \frac{ {x}^{2} }{ {x}^{ - 2} } \\ \frac{ {(5 \times 5 \times 5)}^{3} }{ {(5 \times 5)}^{2} } = {x}^{2 - ( - 2)} \\ \frac{(5 \times 5 \times 5)(5 \times 5 \times 5)(5 \times 5 \times 5)}{(5 \times 5)(5 \times 5)} = {x}^{4} \\ {(5 \times 5)(5 \times 5 \times 5)} = {x}^{4} \\ 25(125) = {x}^{4} \\ 3125 = {x}^{4} \\ \sqrt[4]{3125} = x \\ x = 7.476743906$
